茶芽枯病
tea bud blight
茶芽枯病(tea bud blight)20世纪70年代发现为害芽叶的新病害之一。分布于浙江、江苏、安徽、湖南等省,国外未见报道。 症状先在叶尖或叶缘产生黄褐色病斑,以后扩大成不规则形、无明显边缘的病斑,后期其上产生黑色细小粒点,以叶正面居多。病叶易破裂扭曲。幼芽受害后呈褐色或黑褐色焦枯状。病梢生长受阻,直接造成春茶减产。 病原叶点菌学名为黝夕“ostl’c勿sP.,属球壳抱目球壳抱科无色单胞簇叶点菌属。病菌的分生抱子器球形或扁球形,揭色至暗褐色,直径90一245微米,器壁薄,膜质,孔口直径23.4一46.8微米。分生抱子椭圆形或卵形,两端圆,无色,单胞,内有1一2个绿色油球,周围有一层枯液,长宽为1 .6一4X2.3一6.5徽米,尚未发现病菌的有性世代。 俊染规律病菌以菌丝体或分生胞子器在病叶、越冬芽叶中越冬。次年3月底至4月初,气温上升至10’C左右,开始形成器抱子。抱子成熟后,借助雨水、风进行传播,侵染幼嫩芽叶。经过2一3天后,形成新病斑。4月中旬至5月上旬,平均气温在15一20’C之q分生粉放大间.最利一于病害的发展。6月份以后,由f气温升高至29℃以上,病害停止发展。本病属低温病害,主要在春茶期发生。茶树的生长状况与发病有关,凡早春萌芽期遭受寒流侵袭的茶树,由于抗病力降低,易感染芽枯病。品种间有明显的抗病性差异,以发芽偏早的品种如碧云、福鼎种以及抗逆性差的品种如大叶长、大叶云风发病较重;发芽迟的品种如福建水仙、政和、大毫茶等品种发病较轻。 防治及时分批多次采摘,以减少浸染来源。因地制宜选用抗病品种。秋茶结束后和春茶萌芽期,发病严重的茶园在发病初期喷用70%甲钱托布津可湿性粉剂1500倍液,或50%多菌灵1以)0倍液防治1~2次。I口走六书.沙户、
